Are we sure that touchpads with image sensors will never implement them? -- Dmitry
All image sensors that I am aware of are clickpads, with one button integrated under the pad, which is reported as the middle button. We could report right, middle, up, down, and ext_buttons (scroll is not possible, since w=2;buf[1] is used for x for devices that send agm packets). However, I have no way of knowing if this added complexity is necessary, nor any way of testing it. -Dan -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
